A big box contains 80 red toys and 35 blue toys. Assume sampling is done with replacement, and that we are selecting toys at random: A. What is the probability of selecting a blue toy? B. What is the probability of selecting a red toy and then a blue toy? C. What is the distribution that best describes this data? Can this distribution be approximated

we get in these five samples?
